The present invention relates to a wheel support device. More particularly, the present invention relates to a wheel support device for a suitcase.
Referring to FIG. 1, a conventional wheel support device is disposed on a suitcase (not shown in the figure). The conventional wheel support device has a rectangular longitudinal casing 2, a rectangular transverse casing 1, and a convex housing 3. The convex housing 3 has a through hole 4. A wheel 5 is disposed on a bottom of the convex housing 3. The wheel 5 has a center hole 6. A pivot shaft 7 fastens the convex housing 3 and the wheel 5 pivotally through the through hole 4 of the convex housing 3 and the center hole 6 of the wheel 5.
An object of the present invention is to provide a wheel support device which has a colored triangular plate to reinforce the wheel support device.
Another object of the present invention is to provide a wheel support device which has a colored triangular plate to decorate the wheel support device.
Accordingly, a wheel support device has a triangular longitudinal portion, a triangular transverse casing, and a convex wheel housing portion. The convex wheel housing has a through hole. A wheel is disposed in the convex wheel housing portion. The wheel has a center hole. A pivot shaft for rotatably fastening the wheel to the convex housing to wheel portion by insertion the through hole of the convex housing and the center hole of the wheel. The triangular longitudinal portion has a generally triangular shaped recess, a circular hole, and two round apertures. A colored triangular plate is inserted in the generally triangular shaped recess of the triangular longitudinal portion. The colored triangular plate has a post for insertion into the circular hole of the triangular longitudinal casing and two columns for insertion into the round apertures of the triangular longitudinal portion.
FIG 1 is a perspective exploded view of a wheel and a conventional wheel support device of the prior art;
FIG. 2 is a perspective exploded view of a wheel and a wheel support device of a preferred embodiment in accordance with the present invention; and
FIG. 3 is a sectional assembly view of a wheel and a wheel support device of a preferred embodiment in accordance with the present invention.
Referring to FIGS. 2 and 3, a wheel support device has a triangular longitudinal portion 11, a triangular transverse portion 15, and a convex wheel housing portion 10.
The convex wheel housing portion 10 has a through hole 101. A wheel 30 is disposed in the convex wheel housing portion 10. The wheel 30 has a center hole 31. A pivot shaft 40 for rotatably fastening the wheel 30 to the convex wheel housing portion 10 by insertion into the through hole 101 of the convex housing 10 and the center hole 31 of the wheel 30.
The triangular longitudinal portion 11 has a generally triangular shaped recess 12, a circular hole 14, and two round apertures 13.
A colored triangular plate 20 is inserted in the groove 12 of the triangular longitudinal portion 11.
The colored triangular plate 20 has a post 22 for insertion into the circular hole 14 of the triangular longitudinal casing 11 and two columns 21 for insertion into in the round apertures 13 of the triangular longitudinal portion 11.
The present invention is not limited to the above embodiments but various modification thereof may be made. Furthermore, various changes in form and detail may be made without departing from the scope of the present invention.
